Pineda throws successful bullpen session

The right-hander began the season on the 15-day disabled list with tendinitis in his right shoulder.

"He'll have another bullpen, and then we'll go from there," Girardi said after the Yankees' 7-3 loss to the Twins on Monday night. "I think he threw a 25-30-pitch bullpen -- 28 is the number that's coming up in my head. He threw all his pitches, and he'll throw another bullpen in probably two to three days."

The 23-year-old Pineda, who came over from Seattle in an offseason deal for top prospect Jesus Montero, was 9-10 with a 3.74 ERA in his rookie season with the Mariners last year. He was 1-0 with a 5.68 ERA in six starts (19 innings) during Spring Training.
